It allows him to calculate amazing feats. Alex's power brings him to the attention of Dr. X, an evil genious who wants to conquer the world. Dr. X plans to steal Alex's power and use it for his own purposes. To this end he uses Brandon Caine, Alex's long time friend, as bait to lure Alex to his secret base. Dr. X's plan fails, but Brandon was transformed into Dr. Gangrene. Dr. X and Gangrene team up with the ninja Asazi and the weather controlling Tempest to conquer the world. Can Action Man stop this threat?
